Map of Blaxland's route across the Mountains in 1813, produced by Frank Walker (who was President of Australian Historical Society) from the book Journal of Gregory Blaxland - A Journal of a tour of discovery across the Blue Mountains, New South Wales, in the year 1813 by Gregory Blaxland, with references and explanatory notes, maps, etc by Frank Walker. The 1913 route of the Great Western Highway seems to differ greatly from the present alignment. [1813]
